Justification
This species has a limited distribution range, with an extent of occurrence (EOO) of 5822 km², and an area of occupancy (AOO) of 136 km². It is declining across its range due to ongoing habitat loss and degradation, but is still locally common in remnant fragments of renosterveld, occurring at more than 10 locations. Therefore, it nearly meets the thresholds for Vulnerable under criterion B and is assessed as Near Threatened.

South African endemic

Western Cape
Range
The species is endemic to South Africa and is found in the Tulbagh and Malmesbury Districts of the Western Cape.
Habitat and Ecology
Major system
Terrestrial
Major habitats
Swartland Shale Renosterveld, Breede Shale Renosterveld, Swartland Granite Renosterveld, Breede Shale Fynbos
Description
It occurs on clay or granitic gravel flats and slopes in renosterveld. Flowers are pollinated by hopliine scarab beetles.
Threats
About 70% of this species' habitat is already irreversibly modified due to agriculture and urban development. Loss continues at a very low rate due to agriculture, especially vineyards and olive cultivation. Alien invasive plants (wattles, pines, silky needle-bush, syringa and gums) are a severe ongoing threat. Other threats include grazing and roadside disturbance.
Population

This species is locally common in renosterveld. From 2015, more than 15 new locations were recorded, however, the species is still threatened within its range. The current population size is unknown. However, a continuing decline is inferred from ongoing habitat loss and degradation.
